SPRING HINGE Godfrey E. Sundell, Ri dg way, Pa. Application April 28, 1939, Serial No. 270,533 I 3 Claims. (01. 16-149) This invention relates to spring hinges and is The ends 24 of each of the lugs is then bent j directed particularly to detachable locking hinges towards the body of the leaves to conveniently for screen doors, storm windows and the like received in the recesses II and I5.

It will be apparent from the foregoing description taken in connection with the single embodiment of the invention shown in the drawing that I have provided a spring hinge which is simple in construction and adapted to a variety of uses.

I claim:

1. A hinge comprising a pair of pivoted leaves,

a locking lug on at least one of said leaves, said lug having a connecting portion extending from the leaf body substantially at a right angle thereto, a central portion extending from the connecting portion to form a right angled shoulder therewith, said central portion lying substantially parallel to and out of the plane of theleaf body,

an upwardly extending portion forminga right angled shoulder with the central portion, and a free end portion extending at an angle away from the upwardly extending portion and lying out of the plane of the-leaf body and central portion, in combination with a plate having a slot therein for receiving the central portion of the lug inlocking engagement with said right angled v a, shoulders.

2 A hinge comprising a pair of hinge leaves having cooperating aligned sleeves, pintle means extending through said sleeves providing a pivotal connection, lugs on said leaves, each lug having I receiving the central portion of the lugs and locking'the hinge leaves in fixed position.

3. A'hinge comprising a pair of hinge leaves 1 having cooperating aligned sleeves, pintle means extending through said sleeves providing a pivotal connection, lugs on said leaves, .each lug having a connecting portion extending substantially at a right angle from each leaf body, a central portion extending at a rightangle from-the connecting portion and substantiallyparallel to and out of the plane of the leaf, an upwardly extending portion forming a right angle lockingshoulder with the central portion and a free endpor tion extending at an angle away-from the upwardly extending portion to be disposed out of,

the plane of said central portion and leaf body. GODFREY E, SUNDELL.
